They shared an epitaph of sorts on Facebook yesterday (March 7), labelling Black Sabbath's official lifespan: "1968-2017." It was hashtagged with a simple #TheEnd.

The band was originally formed in 1968 by Ozzy Osbourne, Tony Iommi, Geezer Butler and Bill Ward. "The End Tour" featured Osbourne, Iommi and Butler, with Tommy Clufetos filling in on drums amidst a very public feud between the band and Ward.

During the final tour, Osbourne revealed that Sabbath had no plans to do another album, claiming "People aren't really interested in hearing new stuff" and that they'd rather go out on a "high note." If that holds true, 2012's 13will stand as the group's swan song.
